Definitions

  • the proposed invention is referred to a new system of the photovoltaic solar energy installation.
  • the main object of the present invention is a new way of installing photovoltaic modules.
  • the invention proposes raising the photovoltaic solar installation, making it independent of the topography and land use. For this we would use the 3 rd dimension (z) to escape the restrictions imposed by the terrain (x, y).
  • the photovoltaic modules are mounted on a metal structure, which in turn is suspended from at least two supporting steel cables (closed or semi-closed), whose ends are anchored and supported by a structure (metallic, concrete, or anchored to a rock slope).
  • a structure metallic, concrete, or anchored to a rock slope.
  • this invention clearly exceeds the field of application of agro photovoltaic.
  • this option not only makes it possible to counteract the scarcity of usable space, but also contributes to the sustainable development of rural areas, since its inhabitants have the opportunity to develop new sources of income without losing the productivity and uses of their land.
  • This invention can also be used to allow the deployment of photovoltaic energy on roads, highways, parking lots, railway lines, rivers, irrigation channels, mining operations (active and/or restored), mineral storage parks, logistic areas... because of the possibility of salving large bays without the need for intermediate supports and, therefore, without interfering with the activities previously implemented in an area, thus providing an additional source of income to its owners, or generating all or part of the energy that they need for their processes (auto-consumption).
  • This invention it will be achieved that large areas, currently unproductive from the point of view of photovoltaic electricity generation, will be able to be used for renewable electricity generation and this contributes significantly to achieving the energy independence of our country and the decarbonisation objectives of the economy.
  • this invention can also be used for, in addition to generation photovoltaic solar energy, contribute to concealing the visual impact of landfills, difficult-to-restore slopes in quarries and/or mining operations, large transport infrastructures, logistics areas, business parks, industrial complexes...
  • Another possible application of this invention would be to, in addition to generating photovoltaic solar energy, protect crops, fruit trees, water masses and populations in areas of high solar irradiation by acting partially as a sunshade.
  • the support structures (3) will be assembled at the ends of the steel supporting cables (2). These structures can be metallic, concrete or one, or both, ends of the supporting cables can be anchored to a rocky slope. Subsequently, the two steel supporting cables (2), closed or semi-closed type cables, and the two steel traction cables (7) will be installed. Depending on the difference in height between both ends of the installation, the steel traction cable can be open or closed (option represented in Figures 5, 6 , 7 and 8 ).
  • two support carriages (6) are mounted on each steel supporting cable (2), they are joined by means of the union bar (9), which is perpendicular to both supporting cables, and which is bolted to one of the lower ends of the cars.
  • Each support carriage (6) is then connected to the steel traction cable (7).
  • a group of photovoltaic modules (1) mounted on a metallic structure (4) is suspended.
  • the function of the metallic structure (4) is to serve as a support for the photovoltaic modules and to prevent any mechanical effort from acting on them that could degrade them. Its design will depend on the number of modules, the distance between supporting cables, and especially the climatic conditions of the area where the installation will be located (wind, snow, thermal loads, corrosion).
  • the metallic structure (4) has 4 points of suspension of the structure (5).
  • the two upper suspension points of the structure (5) are connected to two supports (10) by means of a system that allows the rotation of the metallic structure (4) on the horizontal axis (11).
  • Each fixed support (10) is L-shaped and is bolted/welded to the support carriage (6).
  • the design of the suspension points of the structure (5) and of the fixed support (10) must allow absorbing both axial and radial loads.
  • the steel traction cable (7) is activated to drag the first set of support carriages (6) + metallic structure (4) until it allows the longitudinal connection bars to be assembled between two support carriages (12.1). This connection allows rotation about an axis perpendicular to the longitudinal plane of the supporting carriage (6). In this way, the assembly of more support carriages (6) + metallic structure (4) sets is proceeded successively, as can be seen in the upper part of Figure 6 .
  • the angle of the metal structures (4) can be adjusted, and therefore, the angle of the photovoltaic modules (1) to maintain the optimum inclination of the panels, both in winter and in summer (see also figure 10 ).
  • the wiring that connects the different groups of photovoltaic modules together is installed, as well as the necessary electrical apparatus.
  • Ducts and electrical apparatus boxes suitable for the climatic conditions of the area in which the installation will be located will be used, which will be fixed to the longitudinal connection bars between two support carriages (12.1) to prevent them from suffering mechanical stress during deployment and/or operation of the installation.
  • connection bars (12.1) can have different length, since to connect two sets (bar 12.1-2 figure 6 ) of 4 support carriages + 1 metallic structure, it is not necessary to maintain the same distance as between support carriages of an individual set (bar 12.1-1 figure 7 ).
  • the slope of the photovoltaic modules is given by the slope of the steel supporting cable (2). Since the slope along a cable suspended from its ends (catenary) will never be constant, the ability to adjust the slope of the panels will be decisive in maintaining the optimum inclination of the panels, both in winter and in summer, and especially in installations with large bays and/or unevenness, or if cables with little tension are used.
  • the fixed support (10) is replaced by a spindle (13) in the lower support carriage (4). The minimum length of this spindle is equal to that of the fixed support (10).
  • the stroke of the spindle (13) will be chosen based on the difference between the slope of the closed steel supporting cable (2) with respect to the optimal angle of inclination of the panel (30° in the case of figure 8 ).
  • this spindle (13) can be replaced by a cylinder, or another type of device, which also allows us to vary the angle of inclination of the photovoltaic modules with respect to the slope of the cable.
  • this regulation can be manual (acting on each spindle), or it can be automated acting at a distance by means of solenoid valves or servomotors. In the case of slopes of less than 30°, the adjustment procedure is the same, but the adjustment is made on the upper support carriage. (4).
  • the support structures (3) will be mounted at the ends of the steel supporting cables (2).
  • These structures can be metallic, concrete, or one, or both, of the ends of the supporting cables can be anchored to a rocky slope.
  • the 2 steel supporting cables (2), closed or semi-closed type cables will be installed.
  • the use of steel tractor cables is not necessary.
  • the fixed carrying supports (14) that embrace the steel supporting cables (2) are mounted in pairs and tightened by means of at least 4 screws. Subsequently, the carrying supports are joined by means of the union bar (16), which is perpendicular to both fixed carrying supports, and which is screwed to the hanging plate (15). Subsequently, the groups of photovoltaic modules (1) mounted on a metal structure (4) will be suspended, through the upper suspension points of the structure (5), which are connected to the support (17) by means of a system that allow the rotation of the metallic structure (4) on a horizontal axis. Said fixed support (17) is L-shaped and is bolted/welded to the hanging plate (15).
  • lower connection bars (20) will be mounted to longitudinally join the lower suspension points of the structure (5). Acting on one of the ends of the line of lower longitudinal connection bars (20) the angle of the metal structures (4) can be adjusted, and therefore, the angle of the photovoltaic modules (1) to maintain the optimal inclination of panels.
  • a second pair of fixed carrying supports (14) will be mounted to suspend the metal structure (4) also by its structure lower suspension points (5), dispensing with the lower connection bars (20).
  • This second pair of fixed carrying supports (14) will also be joined by means of the connecting bar (16), which is perpendicular to them.
  • the fixed support (17) is replaced by a spindle (13) in one of the (14) fixed carrying supports, either the lower one (slopes greater than 30°) or the upper one (slopes less than 30°) of each group of photovoltaic modules.
